A Study on Mass Spectra of Organophosphorous Compounds (Ⅵ) ——The EIMS and CIMS of Derivatives of Phosphorodiamidoates;

To review the QSAR model between the structure of Bis-sulfonamides and their activity, and to provide reference for the synthesize of Bis-sulfonamides as new endothelin receptor antagonist.

The mass spectra of phosphodiamidoates have been studied using positive ion FABMS and negative ion FABMS.

In this paper, the bacteriostatic activity tests on Escherichia coli and Staphylococcus aureus of 4 kinds of benzenylsulfonylamide compounds were carried out.
